2.2.2 EVENT COUNTERS
For diagnosis purpose, event counters provide number and duration of overloads. When there is a short
circuit on the bus, the load will be disconnected from the output automatically. Number of short circuits
and duration of load detachment are available details. The same applies for the number of KNX bus resets
and of device startups, and for operating times. Additional alarms also provide the number of a value
being in the threshold range and the duration of such event.

2.2.3 EVENT COUNTER RESET
Counters for total operating time and device startups cannot be reset. Other counters for events can be
reset by communication object. These counters (number and duration) are set to zero by writing a

The event counter of each individual alarm (1,2,3,4) is set to zero by writing a
